Excursion Result Tile

How the excursion result tile reports peak cone movement and driver-limit status.

Direct answer

The excursion tile reports peak cone movement and whether driver excursion is the current headroom-limiting condition.

What it measures

• Peak cone excursion in millimeters.
• The frequency where peak excursion occurs.
• Whether the headroom policy is currently limited by driver excursion.

Why it matters

• Cone excursion is a primary driver failure and distortion constraint at low frequencies.
• It shows whether extra power is likely to become sound or just extra movement.
• It helps size high-pass filters and tuning choices.

How to read it in 00 Simulator

• Compare the peak excursion value with the driver Xmax and any Xmech or Xdamage references.
• Open the excursion graph to see whether the peak is narrow, broad, or caused by content below tuning.
• For vented designs, pay special attention below Fb where cone control drops quickly.

What good, warning, and bad usually look like

Good

Peak excursion stays comfortably below the target limit across the intended band.

Warning

Excursion only exceeds target in a narrow region that may be controllable with filtering.

Bad

Excursion exceeds the mechanical limit through the intended operating range.

Common false conclusions

• A single peak value does not tell you whether the whole passband is safe.
• Staying under Xmax does not guarantee low distortion for every driver.
• Excursion margin at 1 W does not imply margin at real playback power.

App behavior notes

• The internal simulation API exposes this as the `excursion` tile.
• The detailed excursion graph converts simulation meters to millimeters for display.
